Important Safety Information

11/13/19

Important Safety Information

Listed below are common practices that may or may not be applicable to the products

described in this manual.



Safety at All Times

Careful operation is your best

assurance against an accident.

All operators, no matter how much

experience they may have, should

carefully read this manual and

other related manuals, or have the

manuals read to them, before

operating the power machine and

this attachment.

OFF

Safety Precautions for

Children

Tragedy can occur if the operator

is not alert to the presence of

children. Children generally are

attracted to attachments and their

work.

 Never assume children will remain

where you last saw them.

 Keep children out of the work area

and under the watchful eye of a

responsible adult.

 Be alert and shut the attachment

and skid steer/track loader down if

children enter the work area.

 Never carry children on the power

machine or attachment. There is

not a safe place for them to ride.

They may fall off and be run over

or interfere with the control of the

power machine.

 Never allow children to operate the

power machine, even under adult

supervision.

 Never allow children to play on the

power machine or attachment.

 Use extra caution when backing

up. Before the power machine

starts to move, look down and

behind to make sure the area is

clear.

Skid Steer Shutdown

And Storage

 Reduce engine speed and shut-off

all power to the attachment.

 Park on solid, level ground and

lower attachment until it is flat on

the ground or support blocks.

 Turn off engine, and remove

switch key to prevent unauthorized

starting.

 Relieve all hydraulic pressures.

 If included, raise seat bar and

move controls until both lock.

 Wait for all components to stop

before leaving operator’s seat.

 Use steps, grab-handles and

anti-slip surfaces when stepping

on and off the skid steer.

 Detach and store attachment in an

area where children normally do

not play. Secure attachment by

using blocks and supports.

Look for the Safety Alert Symbol

The SAFETY ALERT SYMBOL indicates there is a

potential hazard to personal safety involved and extra

safety precaution must be taken. When you see this

symbol, be alert and carefully read the message that

follows it. In addition to design and configuration of

equipment, hazard control, and accident prevention are

dependent upon the awareness, concern, prudence, and

proper training of personnel involved in the operation,

transport, maintenance, and storage of equipment.

Be Aware of

Signal Words

A signal word designates a degree or

level of hazard seriousness. The

signal words are:

Indicates a hazardous situation that, if

not avoided, will result in death or

serious injury.

Indicates a hazardous situation that, if

not avoided, could result in death or

serious injury.

Indicates a hazardous situation that, if

not avoided, may result in minor or

moderate injury.

WARNING

CAUTION

DANGER

Important Safety Information

11/13/19

Dig Safe - Avoid

Underground Utilities

 USA: Call 811

CAN: digsafecanada.ca

Always contact your local utility

companies (electrical, telephone,

gas, water, sewer, and others)

before digging so that they may

mark the location of any

underground services in the

area.

 Be sure to ask how close you can

work to the marks they

positioned.

Listed below are common practices that may or may not be applicable to the products

described in this manual.

Transport Safely

 Comply with federal, state, and local

laws.

 Use towing vehicle and trailer of

adequate size and capacity. Secure

equipment towed on a trailer with

chocks, tie downs, and chains.

 Sudden braking can cause a towed

trailer to swerve and upset. Reduce

speed if towed trailer is not equipped

with brakes.

 Avoid contact with any overhead

utility lines or electrically charged

conductors.

 Always drive with load on end of

loader arms low to the ground.

 Always drive straight up and down

steep inclines with heavy end of skid

steer on the “uphill” side.

 Engage park brake when stopped on

an incline.

 Maximum transport speed for an

attached equipment is 20 mph. DO

NOT EXCEED. Never travel at a

speed which does not allow

adequate control of steering and

stopping. Some rough terrains

require a slower speed.

 As a guideline, use the following

maximum speed weight ratios for

attached equipment:

20 mph when weight of attached

equipment is less than or equal to

the weight of machine towing the

equipment.

10 mph when weight of attached

equipment exceeds weight of

machine towing equipment but not

more than double the weight.

 IMPORTANT: Do not tow a load that

is more than double the weight of the

vehicle towing the load.

Practice Safe Maintenance

 Understand procedure before doing

work. Refer to the Operator’s Manual

for additional information.

 Work on a level surface in a clean

dry area that is well-lit.

 Lower attachment to the ground and

follow all shutdown procedures

before leaving the operator’s seat to

perform maintenance.

 Do not work under any hydraulic

supported equipment. It can settle,

suddenly leak down, or be lowered

accidentally. If it is necessary to work

under the equipment, securely

support it with stands or suitable

blocking beforehand.

 Use properly grounded electrical

outlets and tools.

 Use correct tools and equipment for

the job that are in good condition.

 Allow equipment to cool before

working on it.

 Disconnect battery ground cable (-)

before servicing or adjusting

electrical systems or before welding

on equipment.

 Inspect all parts. Make certain parts

are in good condition & installed

properly.

 Replace parts on this attachment

with genuine Kubota parts only. Do

not alter this attachment in a way

which will adversely affect its

performance.

 Do not grease or oil attachment

while it is in operation.

 Remove buildup of grease, oil, or

debris.

 Always make sure any material and

waste products from the repair and

maintenance of the attachment are

properly collected and disposed.

 Remove all tools and unused parts

from the equipment before

operation.

Tire Safety

 Tire changing can be dangerous

and must be performed by

trained personnel using the

correct tools and equipment.

 Always maintain correct tire

pressure. Do not inflate tires

above recommended pressures

shown in the Operator’s Manual.

 When inflating tires, use a clip-on

chuck and extension hose long

enough to allow you to stand to

one side and NOT in front of or

over the tire assembly. Use a

safety cage if available.

 Securely support the attachment

when changing a wheel.

 When removing and installing

wheels, use wheel handling

equipment adequate for the

weight involved.

 Make sure wheel bolts have been

tightened to the specified torque.

Important Safety Information

11/13/19

These are common practices that may or may not be applicable to the products described in

this manual.

Prepare for Emergencies

 Be prepared if a fire starts.

 Keep a first aid kit and fire

extinguisher handy.

 Keep emergency numbers for

doctor, ambulance, hospital, and

fire department near phone.

911

Avoid High

Pressure Fluids Hazard

 Escaping fluid under pressure

can penetrate the skin causing

serious injury.

 Relieve all residual pressure

before disconnecting hydraulic

lines or performing work on the

hydraulic system.

 Make sure all hydraulic fluid

connections are tight and all

hydraulic hoses and lines are in

good condition before applying

pressure to the system.

 Use a piece of paper or

cardboard, NOT BODY PARTS,

to check for suspected leaks.

 Wear protective gloves and

safety glasses or goggles when

working with hydraulic systems.

 DO NOT DELAY. If an accident

occurs, see a doctor familiar with

this type of injury immediately.

Any fluid injected into the skin or

eyes must be treated

within a few hours or

gangrene may

result.

Wear Personal Protective

Equipment (PPE)

 Wear protective clothing and

equipment appropriate for the job

such as safety shoes, safety

glasses, hard hat, and ear plugs.

 Clothing should fit snug without

fringes and pull strings to avoid

entanglement with moving parts.

 Prolonged exposure to loud noise

can cause hearing impairment or

hearing loss. Wear suitable

hearing protection such as

earmuffs or earplugs.

 Operating equipment safely

requires the operator’s full

attention. Avoid wearing

headphones while operating

equipment.

Use Safety

Lights and Devices

 Slow moving tractors, skid steers,

and self-propelled machines can

create a hazard when driven on

public roads. They are difficult to

see, especially at night. Use the

Slow Moving Vehicle (SMV) sign

when on public roads.

 Flashing warning lights and turn

signals are recommended

whenever driving on public roads.

Keep Riders Off

Machinery

 Never carry riders on skid steer

or attachment.

 Riders obstruct operator’s view

and interfere with the control of

the power machine.

 Riders can be struck by objects

or thrown from the equipment.

 Never use skid steer or

attachment to lift or transport

riders.

Use Seat Belt and ROPS

 Kubota recommends the use of a

CAB or roll-over-protective-

structures (ROPS) and seat belt

in almost all power machines.

Combination of a CAB or ROPS

and seat belt will reduce the risk

of serious injury or death if the

power machine should be upset.

 If ROPS is in the locked-up

position, fasten seat belt snugly

and securely to help protect

against serious injury or death

from falling and machine

overturn.

Important Safety Information

11/13/19

Avoid crystalline Silica

(quartz) Dust

Because crystalline silica is a basic

component of sand and granite,

many activities at construction sites

produce dust containing crystalline

silica. Trenching, sawing, and boring

of material containing crystalline

silica can produce dust containing

crystalline silica particles. This dust

can cause serious injury to the

lungs (silicosis).

There are guidelines which should

be followed if crystalline silica

(quartz) is present in the dust.

 Be aware of and follow OSHA

(or other local, State, or Federal)

guidelines for exposure to airborne

crystalline silica.

 Know the work operations where

exposure to crystalline silica may

occur.

 Participate in air monitoring or

training programs offered by the

employer.

 Be aware of and use optional

equipment controls such as water

sprays, local exhaust ventilation,

and enclosed cabs with positive

pressure air conditioning if the

machine has such equipment.

Otherwise respirators shall be worn.

 Where respirators are required, wear

a respirator approved for protection

against crystalline silica containing

dust. Do not alter respirator in any

way. Workers who use tight-fitting

respirators can not have beards/

mustaches which interfere with the

respirator seal to the face.

 If possible, change into disposable

or washable work clothes at the

work site; shower and change into

clean clothing before leaving the

work site.

 Do not eat, drink, use tobacco

products, or apply cosmetics in

areas where there is dust containing

crystalline silica.

 Store food, drink, and personal

belongings away from the work

area.

 Wash hands and face before eating,

drinking, smoking, or applying

cosmetics after leaving the exposure

area.

Listed below are common practices that may or may not be applicable to the products

described in this manual.

Handle

Chemicals Properly

 Protective clothing should be

worn.

 Handle all chemicals with care.

 Follow instructions on container

label.

 Agricultural chemicals can be

dangerous. Improper use can

seriously injure persons, animals,

plants, soil, and property.

 Inhaling smoke from any type of

chemical fire can be a serious

health hazard.

 Store or dispose of unused

chemicals as specified by the

chemical manufacturer.

bar lowered when equipped and seat belt properly fastened.

The operator can be pinched, crushed, or thrown if not

properly seated in the cab or if operating loader arms from

outside the cab.

• Keep attachment, loader arms, and/or load away from

overhead electrical power lines. Place an orange warning

sign under overhead lines indicating type of danger above.

• Keep attachment, loader arms, and/or load away from

overhead electrical power lines. Place an orange warning

sign under overhead lines indicating type of danger above.

• A crushing hazard that can cause serious injury or death

always exists around power equipment.

• The operator of this attachment must know how to control

the power machine with attachment and how to stop them

quickly in an emergency.

• Do not drive up to anyone or an animal in front of a fixed

object such as a wall or bench. Never assume that the power

machine will stop in time.

• Keep bystanders, pets, and livestock away from your work

area. Never allow anyone to go near or under the

attachment or its load. The attachment and/or load can fall.

• Always secure equipment with solid, non-concrete supports

before working under it. Never go under equipment

supported by concrete blocks or hydraulics. Concrete can

break, hydraulic lines can burst, and/or hydraulic controls

can be actuated even when power to hydraulics is off.

WARNING

To avoid serious injury or death:

• Never make contact with underground utilities such as

electrical power lines, gas lines, phone lines, etc. They can

cause serious injury or death from electrocution, explosion,

or fire. If in doubt, call 811 (USA) before digging so that

they can mark the location of underground services in the

area. For contact information, see Dig Safe in the

“Important Safety Information” starting on page 1.

Section 3: Operating Procedures

Operating Checklist

Hazard control and accident prevention are dependent

upon the awareness, concern, prudence and proper

training involved in the operation, transport, storage, and

maintenance of the Stump Grinder. Therefore, it is

absolutely essential that no one operates the unit unless

they are age 16 or older and have read, fully understood,

and are totally familiar with the Operator’s Manual. Make

• Use Stump Grinder for grinding tree stumps only. Do not

use as a ditcher or for any other purpose. The attachment

can come in contact with underground utilities, rock, and

other debris that can damage the cutting wheel/skid steer

and cause serious injury or death.

• Backup alarm must be in good working order to warn

others. Use a backup camera or rear-view mirror that is in

good condition to help see undesirable situations behind the

unit. Drive at a slower speed to compensate for blind spots.

• Hydraulic fluid under high pressure can penetrate the skin

and/or eyes causing a serious injury. Wear protective gloves

and safety glasses or goggles when working with hydraulic

systems. Use a piece of cardboard or wood rather than

hands when searching for leaks. A doctor familiar with this

type of injury must treat the injury within a few hours or

gangrene may result. DO NOT DELAY.

• Allow only persons to operate this attachment who have

fully read and comprehended this manual, who are properly

trained to operate the attachment safely, and who are age 16

or older. Serious injury or death can result from the failure

to read, understand, and follow instructions provided in this

manual.

• Do not travel across inclines where equipment could slip or

roll-over. Consult your power machine Operator’s Manual

for acceptable inclines they are capable of crossing.

• Do not use Stump Grinder to remove material other than

wood. Doing so can cause components to break, solid

objects to be thrown, and breakdowns. Any of these

problems can cause serious injury or death.

• Operate only power machines equipped with a certified

Roll-Over Protective Structure (ROPS) and seat belt. Keep

folding ROPS in the “locked up” position when

appropriate. If ROPS is in the locked up position, fasten seat

belt snugly and securely to help protect against serious

injury or death from falling and machine overturn.

• Never carry riders on the attachment or power machine.

Riders can obstruct the operator’s view, interfere with

controls, be pinched by moving components, become

entangled in rotating components, struck by objects, thrown

about, fall off and be run over, etc.

• Do not abuse equipment. Incorrect use of skid steer and

Stump Grinder can damage equipment structurally and

cause serious injury or death.

• Check hook-up points frequently to make sure skid steer

hitch is properly positioned under the top angle bar, locking

pins are seated in their notches, handles are locked down,

and equipment is in good operating condition.

• Do not carry or lift loads with the Stump Grinder.

• Do not use Stump Grinder as a working platform. Using

grinder as a working platform can cause serious injury or

death.

• Do not use Stump Grinder for lifting front end of skid steer

off the ground. Doing so can damage equipment and cause

injury if exceeding lift capacity of unit.

• Do not use Stump Grinder for pulling objects out of the

ground, for digging into the ground, for prying other

objects, or for pushing and towing other equipment.

• The parts on your Stump Grinder have been specially

designed and should only be replaced with genuine

Kubota

parts. Altering the

grinder can adversely affect its

performance and/or reliability.

• Avoid exposure to dust containing crystalline silica

particles. This dust can cause serious injury to the lungs

(silicosis). Because crystalline silica is a basic component

of sand and granite, many activities at construction sites

produce dust containing crystalline silica. Trenching,

sawing, and boring of material containing crystalline silica

can produce dust containing crystalline silica.

CAUTION

To avoid minor or moderate injury:

• Failure to obey all safety instructions listed below can

result in injury to the operator and other personnel.

• Always lower Stump Grinder to ground level before

dismounting skid steer.

• Always store Stump Grinder in a secure position so that it

will not fall over.

• Follow all recommendations provided by the skid steer

manufacturer when adding counter weights and other

ballast.

• Follow manufacturer’s recommendations when

dismounting and parking the skid steer.

• Do not exceed Stump Grinder specifications for maximum

input power and/or cutting wheel speed. Personal injury

and/or equipment damage can occur.

Transport Safety

WARNING

To avoid serious injury or death:

• Follow all safety precautions when transporting a load. Not

using safe transporting methods can damage the equipment

and cause serious injury or death.

• Always transport loads as close to the ground as possible

without hitting objects. A load carried high could shift

causing the load to fall, tipping of the machine, and/or loss

of control.

• Always travel straight up and straight down inclines. Never

make turns on the incline.

• Transporting loads across inclines, over ramps, on bumpy,

soft, or slippery surfaces reduces machine stability and lift

capacity. Transporting and lifting loads under these

conditions is extremely dangerous. Follow all transport

instructions in your power machine Operator’s Manual.

• When traveling on roadways, travel in such a way that

other vehicles may pass you safely. Use LED lights, clean

reflectors, and a slow moving vehicle sign that is visible

from the back to warn operators in other vehicles of your

presence. Always comply with all federal, state, and local

laws.
